Sandbag model tests are performed in a wave flume to examine the effects of berm-type slopes on the stability of sandbags and wave runup as compared to uniform slopes. Measurements of wave runup, rundown and sandbag response under regular wave action are made for each test run. The uniform and composite slope test results are analyzed using a modified Saville's method which accounts for the overall effects of the slope configuration on the sandbag stability and wave runup.
